CIRCULAR DOOR FOR SAFES.

SPECIFICATION forming part of Letters Patent No. 590,943, datedSeptember 28, 1897. Application filed June 1, 1897. Serial No. 838,876.(No model.)

To all whom it may concern:

Be it known that 1, WILLIAM COREY, a citi zen of the United States, anda resident of Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Circular Doors forBurglar-Proof Safes, of which the following is a specification.

My invention relates to that class of burglar-proof safes provided witha circular door which is opened and closed by screw-threaded connectionbetween theinner face of the door and its jamb and held in the closedposition under guard of a time-lock.

The object of the invention is to provide means to securely hold thedifferent plates of a door together without perforating the outer plate.

The invention will be first fully described in connection with theaccompanying drawings and then particularly referred to and pointed outin the claims. I

In the drawings, Figure 1 is a transverse sectional view of the front ofa safe embodying my invention. The door is shown in hori-' zontaldiametrical section on the right and partly in elevation and partly inradial diagonal section on the left of the vertical center, the-sectionbeing taken through lines as x of Fig. 2. Fig. 2 is a front elevation.

The door in both views is shown in the closed position.

The safe-body A, the support B, secured to the outside of the door, itshandle I), and the crane-hinge C, in which the support is pivoted, areof ordinary construction and so well known that they need not bespecifically described.

Theouter plate of the door D is centrally recessed, the recess extendingabout half-way through the plate, leaving an annular flange (1 extendingaround its inner edge. The inner wall of this flange is tapped toreceive the circular exteriorly-screw-threaded disk or plate E, which isabout the same thickness as the plate D. One half of the plate E isembedded in the plate D, and the other half projects to enter theinteriorly-rabbeted ring F, which is screwed onto the disk or plate E.The inner opening in the ring F is tapped to receive theexteriorly-screwihreaded disk G,

which is screwed down against the plate or disk E. The rabbeted andscrew-threaded ring H is screwed tightly against the inner face of thering F. The ring H is screwthreaded. exteriorly to engage thescrewthreads at in the inner reduced opening of the jamb, whereby thedoor is closed by turning it in one direction and opened to disengagethe ring II from the jamb when turned in the opposite direction in theusual way.

The parts D, E, F, and G may be either of roll-tempered or laminatedsteel and of any number and thickness desired. The engaging collar H ispreferably of cast steel.

In constructing myimproved door, the parts being formed as shown in Fig.1 and the plate D tapped and screw-threaded-in proper place to receivethe bolt f, the ring F also perforated and countersunk on the inner faceto receive the shank and head of said bolt, and the disk G being alsobored and tapped to receive the screw-bolts g, and theinwardlyprojecting flange of the ring or collar H being perforated andcountersunk to pass the shank and embed the heads of said screws r, thedisk or plate E is first screwed tightly into-the plate D and the ring Fthen turned around until its inwardly-projecting flange and its abuttingface fit tightly against the inner faces of the plate D and ring E. Thebolts f are then inserted to prevent unscrewing the ring. The disk G isthen tightly screwed in place in the ring F and against the face of theplate or disk E, the collar I-I screwed tightly down over the said diskG, and the screws g tightened into place, completing the door. It

terior bolts for holding the plates from revolving, but it is evidentthat keys or other means may be employed instead.
